Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

A clay pit is a quarry or mine for the extraction of clay, which is generally used for manufacturing pottery, bricks or Portland cement. Quarries where clay is mined to make bricks are sometimes called brick pits. A brickyard or brickworks is often located alongside a clay pit to reduce the transport costs .
In the same way the next broken line below, the total cost of producing an ounce of fine gold, is composed of the two costs represented in the lower broken lines—the cost of mining an ounce of gold, and of extracting that amount of the precious metal from the rock. The dotted line at the bottom represents the cost of mining a ton of crude rock.
Aug 27, 2019· Extraction from spodumene is expensive but fast, while processing of clay is not yet commercially proven at scale. There are disruptive new lithium extraction technologies being looked at including leaching, solvent extraction, geothermal extraction and electrolysis, but the findings are too inconclusive to be used commercially.
Mining & Processing. Bentonite is surface mined through a process called back-casting where reclamation is performed by filling the mining pits with soils from subsequent pits while the mine is in production. Typically the topsoil layer is about 30 inches deep, which is removed using heavy equipment.

Mining, Metals, & Minerals Processing Equipment. The mining, crushing, washing and drying of many metals and minerals is accomplished by the use of conveyors. Copper, Iron ore, taconite and uranium are metals that are conveyed using KWS Screw Conveyors and Belt Conveyors.
A clay pit is a quarry or mine for the extraction of clay, which is generally used for manufacturing pottery, bricks or Portland cement. Quarries where clay is mined to make bricks are sometimes called brick pits. A brickyard or brickworks is often located alongside a clay pit to reduce the transport costs of the raw material.
Clay processing flow. Clays usually are transported by truck from the mine to the processing plants, many of which are located at or near the mine. For most applications, clays are processed by mechanical methods, such as crushing, grinding, and screening, that do not appreciably alter the chemical or mineralogical properties of the material.

Procuring the clay itself would be easy, but it would need to be leached or roasted in order to extract the lithium. Clay has not yet been exploited as a source of lithium, but analysts say that for American manufacturing purposes, mining lithium-rich clay in Nevada could be almost as cost-effective as importing it from Chile.
